A method and apparatus for adding at least one and preferably two new data entry functions to otherwise conventional flip-type cell phones. One such data entry function is handwritten alpha-numeric entry using the fingertip as the entry device. The other such data entry function is use of the fingertip for point and click. Thus, the apparatus does not require a special tool for data entry. A button or switch added on the side of the phone, permits switching between the two data entry functions. By depressing a button on the side, the user can use the touch pad as a point and click device. This will allow service providers to offer user friendly web pages that look and feel like surfing the web at home or office. The invention also offers the ability to operate both the numeric phone keypad and the touch pad simultaneously.

DETAILED DESCRIPTION The present invention comprises a method and apparatus for adding at least one and preferably two new data entry functions to otherwise conventional flip-type cell phones.
One such data entry function is handwritten alpha-numeric entry using the fingertip as the entry device.

, the user can enter alphanumeric data by hand writing in the touch pad area.
The invention offers the additional advantage of not requiring a special tool such as a pointer or pen.
Due to the relatively large area of the touch pad, the user can enter the data with his or her fingertip.
By depressing a button on the side, the user can use the touch pad as a point and click device.
This will allow service providers to offer user friendly web pages that look and feel like surfing the web at home or office.
The invention also offers the ability to operate both the numeric phone keypad and the touch pad simultaneously.
Also, the invention impacts the overall size only minimally.
The additional height requirement for the touch pad is only 1 mm.
